Operation
• Motor overload (E03) detection is disabled by setting the parameter to 0.0.
Note The default setting for this parameter is the common rated current of the maximum applicable
motor.
3-6-2 DC Injection Braking Function
The DC injection braking function applies a DC voltage to the induction motor for braking control.
• Startup DC Injection Braking Time
This braking is used for stopping and starting a motor rotating by inertia with no regenerative pro-
cessing.
• DC Injection Braking-to-stop Time
Adjust the stop DC injection braking time if the motor rotating does not decelerate to a stop in nor-
mal operation due to inertia. Increasing the DC injection braking time or DC injection braking fre-
quency reduces the time required to stop the motor.
• When starting, acceleration will start after the startup DC injection braking time (P04) has elapsed.
• After decelerating to the DC injection braking frequency (P03) when stopping, DC injection braking
will be applied for the DC injection braking-to-stop time (P05).
